    摘要: A system and method of decrypting is provided. The method includes grouping domain data of the domain for authorized parties, encrypting a group of leaves in the grouped data having a tree structure using a common key, generating first public data, obtaining a common key by decrypting the first public data using a secret key of a link creator and decrypt the groups using the common key and the secret key, generating a, propagating records, generating second public data by encrypting the table using a common key, obtaining a common key by decrypting the first public data and the second public data using a secret key and generating a view by decrypting data received from a method for the link creator using the common key obtained by decrypting the first public data and the second public data using the secret key.

    摘要: To support a shopper to perform self-service shopping by using an electronic shelf label (ESL) while looking at actual items displayed in a store and to expand the functions of the electronic shelf label (ESL) to enable the linkage with other data processing systems expansively. A shopper uses a mobile processing device (typically, a cell phone owned by the shopper) in a store. The functions necessary to obtain contents from the electronic shelf label (ESL) are obtained by introducing an application program into the shopper's own cell phone, by which it is expected that the shopper is able to easily enjoy shopping. When photographing the electronic shelf label (ESL), the contents associated with items are encoded (the price display automatically changes to a barcode) and then decoded.

    摘要: It is one object of the present invention to prevent embedded verification information from being lost even when a quantization process is performed after verification information has been embedded. A pre-embedding portion 32 converts a image data value so that quantized values not changing by error introduced through the embedding process. A hash value calculator 300 calculates a hash value using image data and key information, and a hash value embedding portion 302 embeds the hash value in the image data. An output format converter 304 quantizes the image data in which the hash value is embedded, and generates JPEG data.
